  2. 2. Frequency comb Brillouin microscopy

    Author : Felipe Ademir Alemán Hérnandez; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brillouin light scattering; optics; spinwave spectroscopy; phonon spectroscopy; microscopy; Fabry-Perot interferometer; Frequency comb;

    Abstract : Brillouin light scattering (BLS), an almost a century-old technique, has evolved into a powerful and versatile method to study acoustic and magnetic phenomena down to the nanometer size scale. Presently, BLS can be applied in fields as diverse as acoustics, spintronics, geosciences, and biophysics. READ MORE

  4. 4. Phase-Contrast and High-Resolution Optics for X-Ray Microscopy

    Author : Olof von Hofsten; Ulrich Vogt; Ian McNulty; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Microscopy; X-ray optics; X-ray microscopy; Soft X-ray physics; Optics; Optik; Physics; Fysik;

    Abstract : X-ray microscopy is a well-established technique for nanoscale imaging. Zone plates are used as microscope objectives and provide high resolution, approaching 10 nm, currently limited by fabrication issues. This Thesis presents zone plate optics that achieve either high resolution or phase contrast in x-ray microscopy. READ MORE

  5. 5. Automating STED microscopy for functional and structural live-cell imaging

    Author : Jonatan Alvelid; Ilaria Testa; Eggeling Christian; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; STED; microscopy; nanoscopy; super-resolution microscopy; automation; image analysis; fluorophores; Biologisk fysik; Biological Physics;

    Abstract : Optical microscopy imaging methods are today invaluable tools for studies in life sciences as they allow visualization of biological systems, tissues, cells, and sub-cellular compartments from millimetres down to nanometres. The invention and development of nanoscopy in the past 20 years has pushed fluorescence microscopy down to the nanoscale, reaching beyond the natural diffraction limit of light that does not allow focusing of visible light below sizes of around 200 nm, and into the realm of what was previously only thought possible with electron microscopy.
